Ok, that's the 5e OGL sheet. Honestly, the easiest way to get the attribute names is by (in Chrome) right clicking a number or field and clicking inspect, then looking for something like: <input type="text" name="attr_ passive_wisdom " title="@{passive_wisdom}" value="(10+@{perception_bonus}+@{passiveperceptionmod})" disabled="true" ><span></span> the name="attr_something" tells you the name. Above, the reference would be @{passive_wisdom}. You can use that with @{selected|passive_wisdom} or @{target|passive_wisdom} or if it's in the ability of a character, just straight @{passive_wisdom}.
